Changing Brush Properties “On the Fly”

Mari also includes default keyboard-and-mouse shortcuts to change the relative Radius, Rotation, Opacity, and Squash of the brush you're using.

1.   To change the RADIUS of your brush, press and hold R, and click and hold the left or right button while moving the cursor to increase or decrease the outer radius, and up or down to increase or decrease the inner radius.
2.   To change the ROTATION of your brush, press and hold W, and click and hold the left or right button while moving the cursor to rotate clockwise or counterclockwise.
3.   To change the OPACITY of your brush, press and hold O, and click and hold the left or right button while moving the cursor to increase or decrease the opacity.
4.   To change the SQUASH of your brush, press and hold Q, and click and hold the left or right button while moving the cursor.
